STUDY OF GALVANOSTATIC CHARGE TECHNIQUE USEDFOR METAL CORROSION MONITORING IN SEAWATER

摘要

Two typical metal materials copper and mild carbon steel were used to study galvanostaticrncharge technique which is for metal corrosion monitoring in seawater. A group of Ag/AgX tiny referencernelectrodes were used to determine the polarization potential of different locations of big work electrodes.rnThe corrosion monitoring methods for anomaly metal structure were discussed. To solve no-uniformrnpolarization of big area and complex structure samples, mathematic model was established to obtain thernreal current density at any point. In addition, this technique can monitor the corrosion condition of evenrncorrosion, as well as partial corrosion.
